SPECIFICATION forming part of Letters Tatent No. 634,696, dated October 10, 1899. j Application filed March 7, 1899. Serial No. 708,161. {No model.)

To du whom it may concern,.-

Be it known that I, JOHN C. MIOHIE, a citizen of the United States, residing at Durham,

in the county ot Durham and Stateof North Carolina, have invented a new and useful Improvement in Entrenching-Tools, of whichl v the following is a specification.

This invention is a new and useful con! struction of entrenching-tool adapted to be used in connection with any construction of firearm, but particularly adapted for use in connection with the magazineriiie nou7 in use.

The object of the invention is to provide an entrenching spade or shovel which can be quickly and easily attached to or detached from a bayonet-scabbard.

Another object is to provide anv entrenching shovel or spade which shall be exceedingly strong and durable and will be of such shape that it can be easily carried in the knapsack Without inconvenience. Y

With these objects in view the invention consists in the peculiar construction of the.

various parts and in their novel combination and arrangemennall of which will be fully a longitudinalfsection on an enlarged scale.

Fig. 4 isaftransverse vertical section on the line 4 et of Fig. 2.

In carryingout my'invention I employ a' shovel or spade A, which may be of any 'convenient and suitable size and is preferably made of thin Sheetsteel', as shown, so las to produce the slightly-upturned sides A', the

' upwardly-curved shoulders A2, and the cenf trally-raised portion A3, said raised portion being essentially semi-elliptical in shape, as shown in Fig. 2, and upon the underface of 'the shovel or spade is riveted a depressed plate A4, also seln'ifelliptical in shape, thus producing a socket A5, in the point or apex of Vwhich is secured a metal block B. The socket thus formed is intended to receive the lower end of the bayonet-scabbard, and in practice Fig. 2 is the two.

I prefer to construct the socket of such a size that about six inches of the scabbard will'be received therein, andin order to hold the said scabbard within the socket, and thereby securely connect the same to the entrenching shovel or spade, I employ the inwardly-projecting spring-plates C, which are secured Within the socket and extend toward the metal block B, so that when the point of the scabbard is forced into the socket the ball upon the end of said scabbard will pass between and beyond the spring-plates and be thereby securely fastened in the socket, the ball resting in' a slight depression B', produced in the upper end of the block, and the ends of the springs are also bent slightly out- Wardly, as shown at C', in order to provide a suitablerest and also permit the scabbard to be Withdrawn therefrom by means 'of a quick jerk. The block within the bottom of the l socket greatly strengthens the shovel or spade and also prevents the scabbard being pushed in too far. After the scabbard has been properly inserted the bayonet can be fixed Within the. scabbard, the Wholeforlning a short-handled shovel, and in case a long handle is necessary the bayonet can be aiiixed to the ban rel of the gun. l

If desired, the bayonet can be used for digging preliminary to the shoveling operation, and Vthen by inserting the bayonet into the scabbardthe device can be used as a shovel and the upturned sides and the curved-up shoulders prevent the dirt slipping oit the shovel and also greatly sti ffen andstrengthen y I-Iavng thus fully described my invention, what I claim as new,I and desire to secu re by Letters Patent of the UnitedStates, is-

' l. An entrenching-shovel having a socket adapted to receive the scabbar'd of a bayonet, astop-block arranged at `the bottom of the socket and the fastening-springs for securing the scabbard Within the socket, substantially as shown and described;

' 2. An entrenching-shovel having theV up# turned sides and upwardly-curved shoulders and the centrally-raised portion ,the depressed plate riveted to the bottom of the shovel and providing a socket adapted to receive the bayonet-scabbard, a block secured in the bottom of the socket and the securing-springs also Wmdly-projectiugspring-plates sccued withfastened in the socket adjacent to the bottom in said socket, adapted to engage the end of thereof extending toward each other and also the scabbaid, substantially as described.

toward the stop-block, substantially as shown JOHN C. MICHIE. 5 and described. Witnesses:
